Connectivity problem (to websites)

My internet's working perfectly fine. However, there seems to be a couple of sites in particular that I can't get onto at all.

There's probably a whole load more out there that I can't connect to but so far it's formspring and MySpace.

Also, before Facebook logs in it asks me something about a certificate and I have to click 'okay' before it actually logs in for me. Never used to do that.

I've tried re-setting my router amongst a few other things but I don't have a clue what's up.

Anybody have any ideas?

Wish I could help, Ross but I have no idea with all these stuffs.

Just starting to annoy me really. No idea how to sort it out. Tried a variety of things.

Know i'm late on this one but have you cleared your cache and cookies?

It's all sorted now!

My brother did something with the router I think. I have no idea what, but he did it.

Not a word of a lie. Clicked on this thread and got this!!

I get that about 2-3 times a day. It's really weird.

Only happens here, aswell.
